Tree86 v2.00                    README.T86                  January, 1989
This file contains additions or corrections to the manual.  You may View it 
using Tree86 or use the Utilities, Print, File option to print it.

If you are using a Hercules board or trying to read drives larger than 
67 megabytes, we are working on modules to address these issues.  
If you are interested, let us know.

Page 8 - EXPANDED MEMORY USAGE
If your system includes expanded memory, Tree86 will automatically use it.  
To prevent Tree86 from using expanded memory, you may pass the parameter /0 
on the command line.  EXAMPLE:

	C>Tree86 /0  

Page 16 - INSTANT LOG (available from CONFIG86.EXE)
Be aware that if you have set Instant Log "on", and you make directory changes 
from anywhere outside Tree86 your last data file will be incorrect.  This can 
occur even if you use a different version of Tree86 (like an unconfigured 
version).  If you've removed a directory, you will see a "Path not Found." 
message when you do a Find, or when you try to list a directory that appears 
on the tree but has previously been removed.  If you've added a directory, it
will not appear on the tree.  Relog your drives with CR and 
the drive letter to clean up your data.  It is a good practice to relog your 
subdirectories periodically to insure data integrity.

Further if Instant Log is on and you have configured Tree86 to use the 
Small Memory Model, it will only read in the first 82 subdirectories.  When you 
quit Tree86, the data file that is written will record only the first 82 
subdirectories, and the next time you call up Tree86, it will not give you 
the warning that the tree has been truncated.  Reconfigure with a larger 
memory model, run the newly configured Tree86, then quit to record an 
accurate data file.

Page 16 - MEMORY MODELS (available from CONFIG86.EXE)
The small and medium models can accommodate additional simultaneously logged
drives.  While CONFIG86 limits the number of "automatic" simultaneously
drives, you can log additional drives during a session if you are using the
medium or small model.  The medium model allows 15 drives and the small model
accommodates up to 26 (the DOS maximum) concurrent drives.  The reason for this
inverse relationship stems from our attempts to keep Tree86 compact and to 
avoid the overhead associated with multiple segment data areas for directory 
information.

If you are using the medium or large models and have logged 15 or 10 drives
respectively, you can still log another drive by first unlogging a drive.

Page 22 - USING A MOUSE
The View module accessed by Tree86 now supports the mouse to scroll up or 
down and to Escape.  Press the right button to page down, the left to page up.
Click both buttons simultaneously to escape.

Page 23 - POINT AND SHOOT
After you press [Tab] and select a target window, the tree of the target drive
appears.  If you have made a change in the directory structure, e.g. renamed 
a directory or created a directory, the drive will be reread before the tree
displays otherwise it will display instantly.

Page 31 - XCOPY
If the target of this feature is a previously logged drive, Tree86 will flag
the drive as needing to be relogged and do so the next time it is accessed.
This is necessary because XCOPY alters the subdirectory structure of the
target and renders the data out of date.

Page 32 - PRINT
The print tree feature has been enhanced to include the number of files and
total bytes for each subdirectory.

Page 47 - REXX compatibility
The RUN command recognizes REXX files as legitimate files to execute.

Page 51 - FILE TOO LARGE.
This new message appears when the file you are trying to copy is too large for
any disk in the target drive.  Use a high density disk, another drive, or 
"backup" to copy the file.

Page 52 - PATH NOT FOUND.
This message may also reflect an inaccurate data file caused by changing the
subdirectory structure outside of your configured Tree86.  Relog the drives
to update the data.  (See page 16 above.)

TECHNIQUE:

Before doing an Xcopy, Copy, or Move of tagged files to another drive, 
press Tag Display to list only tagged files.  Now, if during the operation, 
the message "Place next disk in drive _." appears and you do not have a 
prepared diskette, you may easily interrupt the operation to prepare one.  
When the message to replace the diskette appears, press [Esc].  The highlight 
will be on the file that will be copied next.  Use Tag Range to untag the 
files above the highlight (These are the files that have already been 
copied-unnecessary on a Move).  Then, press / to go to Tree-DOS.  At the DOS 
prompt, you can perform any DOS command.  

For example:  If your disks are in drive A, type DIR A: on a different disk 
to see the files.  Then you may delete them (Type DEL A:*.*) or format the 
diskette (Type FORMAT A:).  When you have prepared more diskettes, press / 
again.  Now the list displays with the rest of the tagged files ready to 
continue the operation.  Press Utilities, and the appropriate command plus 
the target (You can use Ctrl R to repeat the path at the dialog box.)  Now 
the operation continues where it left off.
